Application of the Wilcoxon Test to correlate the results of the Saber 11 and Saber T&T Test

Abstract

In Colombia there is a model of monitoring the Quality of Education in which different tests are applied throughout the academic lifecycle of a student, in basic education, secondary education, until finally reaching higher education. Among these tests are: the Saber Test 11 and the Saber T & T Test, among others. The first, applies to students of the last grade of secondary education and the second to students of the last semester of the Technical and Technological program. It is possible to think that a person who obtained good results in the test saber 11, after preparing in a Higher Education program and presenting the corresponding test, should present a notable improvement in their results, if compared with the first exam. The foregoing is not necessarily true, in order to make this statement it is essential to carry out a study that supports this theory. The present research makes use of Test Wilcoxon to compare the means of 2 distributions, for this case particularly : the Saber 11 and Saber T & T tests of the same student. From the Saber 11 test, the generic Mathematical and language competences are chosen, and for the Saber T & T tests, quantitative reasoning and critical reading were selected. The selected population are the students of the Technology in Systems program who took the test in 2012, belonging to the Faculty of Design and Engineering of the Technological Foundation Antonio de Arevalo - TECNAR, they are students, product of the first accreditation of the program.
